FADH2 and NADH
Energy enters a food web by photosynthesis: the sun is the primary energy source, and autotrophs (mainly plants) 'fix' the energy & use it to convert carbon dioxide into foods which are then eaten by organisms further up the food chain.
as sunlight..
Energy enters a food chain in the form of sunlight, and leaves the food chain in the form of heat.

The first stage of photosynthesis is about how the chlorophyll (green pigment) captures the suns energy and stores it. The second stage is about how water enters through the roots of the plant and carbon dioxide enters through the stomata. When this comes together with the energy pre-stored, it creates a chemical reactions, with the products being sugar and oxygen. The sugars are then used by the cell to perform important processes.
in the human body exces glucose enters anabolic pathways and may be converted into glycogen or what
The sun's energy enters the biological world through photosynthesis. Plants capture sunlight and convert it into chemical energy in the form of glucose through this process. This energy is then transferred through the food chain as organisms consume plants or other organisms.
The organisms at the top of the pyramid receive only a small fraction of the energy that originally enters the system.

Ecosystems have an atmosphere, soil, light, heat, water and living organisms. The living organisms in an ecosystem can include plants, animals or both.it is formed by living non living thing.

The original energy in most ecosystems enters through sunlight. Sunlight is captured by plants through the process of photosynthesis, where they convert sunlight into chemical energy. This energy is then passed on to other organisms when they consume the plants or other organisms that have consumed plants.
